Terahertz radiation — the band of the electromagnetic spectrum between microwaves and visible light — has promising applications in medical and industrial imaging and chemical...
Briefs: Test & Measurement
It's difficult to see the details of atomic and topographical changes that lead to battery failure. However a team of researchers developed a method to see reactions leading to a...
Briefs: Mechanical & Fluid Systems
A new type of mechanical instrument was developed to perform complex, minimally invasive procedures, also known as laparoscopic surgery. The technology could lead to less trauma for...
Briefs: Materials
Materials scientists are looking to nature — at the discs in human spines and the skin of ocean-diving fish — for clues about how to design materials with both flexibility and stiffness. The solution...
Briefs: Electronics & Computers
A new, flexible, silicon-on-polymer chip was developed to augment new networked realities such as the Internet of Things. Typical silicon-based integrated circuits are brittle, rigid components packaged in a...
Briefs: Electronics & Computers
Inspired by brains, neural networks are composed of neurons (or nodes) and synapses, which are the connections between nodes. To train a neural network for a task, a neural network takes in a...
Briefs: Electronics & Computers
Shape memory alloys (SMAs) have the unique ability to recover large deformations in response to thermal, mechanical, and/or magnetic stimuli. This behavior occurs by virtue of a crystallo-graphically...
Briefs: Materials
Currently, most 3D-printed organ models are made using hard plastics or rubbers. This limits their application for accurate prediction and replication of the organ’s physical behavior...

Sensor Detects Nuclear Weapon Solvent
A new sensor picks up signatures of tributyl phosphate, a solvent used to enrich uranium, including for use in a nuclear weapon. Enzymes can detect tributyl phosphate signatures, but the lifespan of the enzymes is too short to make them practical for sensors.
Briefs: Imaging
Time of flight is an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor. In time-of-flight imaging, a short burst of light is fired into...
